Rehabs That Take Union Health

Does Union Health Cover Drug and Alcohol Rehab?

Yes. The union fund plans administered by Union Health Service pay for substance use treatment on an inpatient and an outpatient basis, but only at UHS or on a UHS referral. Cost share turns on the fund: Local No. 1 Plan A pays inpatient at 20% coinsurance with a referral, and the SEIU Healthcare IL Home Care plan pays chemical dependency care, inpatient and outpatient, at 100%.

Local No. 1 Supplemental Plan A sits lower again, at 10% coinsurance in network and 20% out of network, both with a UHS referral. The Chicago Metropolitan Security Officers Plan A HMO pays substance use treatment at 80% after the deductible, and only at a UHS-referred facility. The common thread across every one of these documents is the referral: without it, the Local No. 1 plans state there is no coverage at all.

What Does Union Health Pay For at Each Level of Care?

The fund documents describe substance use treatment only as inpatient or outpatient. Detox, residential care, partial hospitalization, intensive outpatient and medication-assisted treatment are not named as separate benefits, so the practical question for the admissions team is which of the two categories a given program bills under. Member Services on 312-423-4200 ext. 7997 is where that is settled.

Medical Detox

Withdrawal management is not itemised in any fund summary, so medical detox delivered in a hospital bed is treated as an inpatient admission and follows the inpatient rules, including the preauthorization step below. UHS lists affiliated hospitals at Advocate Christ, Advocate Condell, Advocate Illinois Masonic, Advocate South Suburban, Rush-Copley, Rush-Oak Park and the University of Illinois Hospital and Health Sciences System. Alcohol and benzodiazepine withdrawal can bring on seizures, and acute withdrawal belongs in an emergency department whatever the referral position.

Residential and Inpatient

An inpatient stay for substance use is covered on Local No. 1 Plan A at 20% coinsurance in network and 30% out of network, in both cases with a UHS referral, and benefits are calculated on the semi-private room rate. A residential rehab admission that a program bills as inpatient should be run past the fund in advance, since the documents do not use the word residential and no medical necessity criteria set – ASAM, InterQual, MCG or LOCUS – is named in any UHS or fund document.

PHP, IOP and Outpatient

Outpatient substance use services carry no charge at UHS on Local No. 1 Plan A, with the deductible waived, then 20% coinsurance at a non-UHS network provider with a referral and 30% out of network with a referral. A partial hospitalization program or an intensive outpatient program run by an outside clinic falls under that outpatient line unless the program bills it as a hospital day, which is worth asking before the first session.

Does Union Health Need Prior Authorization for Rehab?

Yes, in two separate steps. A UHS referral is required for any service provided outside UHS, and on Local No. 1 plans an inpatient or hospital stay must also be preauthorized with Valenz on 1-800-845-7348. Skipping the Valenz call brings a $250 non-preauthorization deductible, and skipping the referral means no benefit is paid.

Referral requests are reviewed for benefits and eligibility by the Medical Management Referral Department, and status can be raised after five to seven working days on 312-423-4200 ext. 7996. On the Chicago Metropolitan Security Officers plan, inpatient hospital care and out-of-state non-UHS care both require a UHS doctor’s referral, and services without one are not covered. The SEIU Healthcare IL Home Care plan tells the member or the program to call Med-Care Management before scheduled treatment.

What Happens Without a UHS Referral?

Nothing is paid. The Local No. 1 summaries state plainly that outpatient mental health and substance use services are not covered unless performed at UHS or upon referral from UHS, and the Chicago Metro plan covers only UHS or UHS-referred facilities. Emergencies are the narrow exception, with their own notification clock.

How Much Does Rehab Cost With Union Health?

It depends on the fund. Local No. 1 Plan A carries a $200 per person and $400 family network deductible, rising to $300 and $600 non-network, with an out-of-pocket limit of $2,500 and $5,000 in network and $3,900 and $7,800 out of network. Inpatient substance use care then runs at 20% coinsurance in network.

Supplemental Plan A is cheaper throughout: a $100 and $200 network deductible, $200 and $400 non-network, out-of-pocket limits of $1,100 and $2,200 in network, and inpatient care at 10%. The SEIU Healthcare IL Home Care plan has no calendar year deductible and a $3,000 medical out-of-pocket maximum, with chemical dependency care paid in full. The Chicago Metro plan sets a $350 deductible per subscriber or child, $700 for a subscriber plus children, and an out-of-pocket maximum of $5,000 and $10,000.

Those are the sums a program bills where no plan is paying. Under a UHS fund plan the member’s share is the coinsurance above, which is why the referral and the Valenz call move the final bill far more than the advertised day rate does.

Does Union Health Cover Suboxone, Methadone and Other Addiction Medication?

The fund documents do not say. The 2026 Union Health Service formulary, which is described as a list of commonly used drugs rather than a complete one, does not name buprenorphine, buprenorphine and naloxone, naltrexone, methadone, naloxone, acamprosate or disulfiram. Only varenicline appears under anti-addiction agents, at the zero tier. UHS tells members to call the number on the ID card for anything not listed.

That makes the medication question the first one to raise, not the last. If a medication-assisted treatment plan is part of the clinical picture, ask whether the drug is dispensed inside the program as a service or filled at a pharmacy, and ask the fund office how Suboxone and buprenorphine or a monthly injection are handled under the plan.

Where the Prescription Is Filled

UHS runs a clinical outpatient pharmacy at its Polk Street Center, with service in English, Polish and Spanish, and a mobile app for refills. The pharmacy network sits with Optum Rx on 866-207-5623, while the SEIU Local No. 1 residential drug benefit lists CVS Caremark. On Local No. 1 Plan A, generics are 20% coinsurance with a $10 minimum at retail, preferred brands 20% with a $25 minimum, non-preferred 20% with a $40 minimum and specialty drugs 20% between $100 and $250, with out-of-network drugs not covered. The Chicago Metro plan uses the UHS formulary only, at a $5 generic and $20 brand copay.

Does Union Health Cover Therapy and Mental Health Care?

Yes. Outpatient mental health care carries no charge at UHS on the Local No. 1 plans, a $10 copay per office visit on the SEIU Healthcare IL Home Care plan, and is paid in full after a $10 copay at a UHS facility on the Chicago Metro plan, which lists annual and lifetime maximums as unlimited with no visit caps.

Psychiatry is the only behavioral specialty listed in the UHS physician search, with no psychology, counseling, social work or addiction medicine specialty named, so ongoing therapy is likely to involve a referral out. The Home Care plan also excludes treatment by a marriage therapist or counselor and sessions with family members, which matters where family work is part of the treatment plan.

Which Rehab Centers in Illinois Are In-Network With Union Health?

A program counts as in-network when a UHS physician has issued a referral to it and it sits in the network the fund uses for care outside UHS clinics, which for Local No. 1 plans is Blue Cross and Blue Shield of Illinois on 1-800-810-2583. Network status is settled by the Medical Management Referral Department on 312-423-4200 ext. 7996, read against the plan named on the card.

Illinois has 690+ listed treatment programs, 533 of which accept Medicaid, concentrated in Chicago, IL, Arlington Heights, IL, Downers Grove, IL and Hinsdale, IL. Programs that accept Union Health are gathered on the Union Health page, and each listing shows the payments the program says it takes, its licensing and accreditation, and how far it sits from the nearest airport, so a shortlist can be drawn up before the referral call. Counts updated October 2026.

How Do I Find a Rehab That Takes Union Health?

Call UHS on 312-423-4200 and ask for an appointment with a UHS physician, since the referral starts there and nothing outside UHS is paid without it. Member Services sits at ext. 7997 or memservices@unionhealth.org, referral status at ext. 7996, and the Local No. 1 Fund Office answers on 1-866-844-0488. The SEIU Healthcare IL Benefits Funds office is on 773-385-9300 or 1-877-734-8543.

UHS care is delivered from six Chicago-area sites: Polk Street at 1634 West Polk Street, 87th Street, Norridge, Oak Park, Evanston and Aurora, all on the same main number. A retiree holding the Union Health Service Medicare Plan is in a Health Care Prepayment Plan rather than a Medicare Advantage product, so UHS physician care and Part B services at UHS facilities run through the plan while hospital and Part A claims go to Original Medicare. No Medicaid managed care product was found under the UHS name, and Illinois Medicaid coverage runs on its own track.

Is Union Health Service the Same as Union Health in Indiana?

No. Union Health Service, Inc. is a Chicago nonprofit chartered under the Illinois Voluntary Health Services Plan Act, first licensed on December 1, 1952, opening its first center on North Wabash Avenue on April 26, 1955 and moving to Polk Street in 1965. It carries about 40,000 members and dependents, 40 full-time primary care physicians and more than 70 part-time specialists, and is listed by the Illinois Department of Insurance as a limited health service organization.

Union Health in Terre Haute is a separate Indiana hospital system with no ownership link to the Chicago plan. If a program in Indiana lists Union Health, it is describing a hospital relationship rather than a payer, which is one more reason to read the card rather than the sign over the door.
